Hi Phani! I can't help with the Crohns but someone else might. However, you don't need the ornithene (sleeping pills). I have never taken them and you can't buy them here in England anyway. I have never had any problems at all and I was terrified of the liver flush. I am a fan now (finished 5th flush) and it is really helping me. This web site and the support of some really great people has been invaluable. Good luck.
